Vitamin A for Thyroid Function

I like to recommend patients consume foods high in Vitamin A or take Cod Liver Oil which is high in Vitamin A because it has so many roles in human biochemistry, and because it is the most neglected and maligned vitamin in the popular literature. New research corroborates the fact that vitamin A is needed for thyroid function. In a four-month trial, fifty-six obese thyroid patients were randomly allocated to receive either 25,000 IU vitamin A per day or a placebo. In addition, twenty-eight non-obese thyroid patients received the vitamin. Vitamin A caused a significant reduction in blood thyroid stimulating hormone (TSH) concentrations in both obese and non-obese patients along with an increase in T3. The researchers con­cluded: vitamin A supplementation might reduce the risk of subclinical hypothyroidism in premenopausal women. How about suggesting the consumption of vitamin A-rich food instead? Let’s reduce the risk of thyroid problems in everyone by encouraging the consumption of foods like liver, cod liver oil and grass-fed butter.
